In our heart, every single cell works as a generator of electrical impulses. When a large number of cells in our heart simultaneously produce electricity, the individual voices of the cells are summed up and added together in a clever way. Well, like a few batteries are inserted into the TV remote so that it works at full power.
All this electrical activity in our heart is easily recorded with an ordinary voltmeter. That is, the cardiograph that gives you the ECG tape is a voltmeter. Expensive, sensitive, but still a voltmeter. It captures the very wave of electricity that many cells in our heart produce at once. Well, or does not fix anything when the heart is resting between two contractions.
Depending on where the electrodes of the cardiograph are attached, you can get some fluctuations in the electricity on the device.
The heart has two atria and two ventricles. The ventricles are larger, and they also generate more electricity. Therefore, when they talk about the electrical axis of the heart, they usually mean the sum of all electrical impulses in the ventricles of the heart, which added together and produced a high tooth on the cardiograph.
Sometimes the direction of this common vector depends on the mechanical position of the heart, and sometimes on the clever mixing of electrical impulses. Roughly speaking, the heart can lie in the chest as usual, but if one of the walls of the heart becomes thicker, then it will generate more electricity. As a result, the electrical axis of the heart will shift.
The electrical axis of the heart is usually measured in the frontal plane. The frontal plane is like a big clock that hangs on your chest.
Usually the electrical axis of the heart is measured in degrees, but for example, it is easier to imagine it as a clock. If the clock is hanging on the chest, then the electrical axis of the heart will be normal anywhere from 2 to 6 hours. That is, at half past five - it's still normal. This does not mean that everything else will be abnormal. There may simply be a deviation of the electrical axis of the heart in one direction. Sometimes it doesn't make any sense.
If the axis of the heart points somewhere between 6 and 9 o'clock, then this deviation is to the right. And if it points to the side between 12 and 2 o'clock, then this deviation to the left. Sometimes electrical impulses are so cleverly summed up that it is impossible to determine the electrical axis of the heart.
Until now, doctors and scientists cannot agree on what exactly is considered a normal electrical axis of the heart, and what is a deviation to the left or to the right.
There can be many reasons for the deviation of the electrical axis of the heart:
Deviation of the electrical axis of the heart to the right
If the electrical axis of the heart points at 6 o'clock, then this is also called the vertical position. And this may well be the norm.
If the heart turns to the right on inhalation, then the electrical axis of the heart will turn to the right. Have you presented?
The heart rests on our diaphragm, as we lie on our right side on the sofa with an arm under our head.
On inhalation, the diaphragm goes down, and the apex of the heart points no longer to half past five, but vertically to the floor. Well, it's as if we were lying on the sofa on our right side, and then we decided to sit down and lowered our legs from the sofa. That is, they turned clockwise.
If the right ventricle of the heart has difficulty pumping blood into the lungs and is pumped from it like an athlete, then its powerful muscle will give out a powerful electrical impulse. The entire electrical axis of the heart will skew from this impulse to the right.
Or a heart attack will rattle the lateral wall of the left ventricle. The cells in it will die and will not be able to produce electrical impulses. In this case, a healthy right ventricle will regularly generate current and will pull the electrical axis in its direction. Got it?
Deviation of the electrical axis of the heart to the left
Maybe normal, especially with age.
As you exhale, the diaphragm rises and the heart rotates counterclockwise. Instead of the left leg, it points with its tip and electric axis to the left hand.
Left ventricular enlargement and everything similar according to the same scenario.
Briefly speaking
A tilted electrical axis does not mean that your heart is painfully turned inside out. She just hints at something that will have to be evaluated in a complex.
